Researchers have linked the travels of a 14,000-year-old woolly mammoth with the oldest known human settlements in Alaska, providing clues about the relationship between the iconic species and some of the earliest people to travel across the Bering Land Bridge. Isotopic data, along with DNA from other mammoths at the...

Climate change threatens global forest carbon sequestration, study finds
Climate change is causing Western U.S. forests to be less effective carbon sinks, even as it boosts the productivity of forests in the Eastern U.S., according to new research.
Scaling up Urban Agriculture: Research Team Outlines Roadmap
Urban agriculture has the potential to decentralize food supplies, provide environmental benefits like wildlife habitat, and mitigate environmental footprints, but researchers have identified knowledge gaps regarding both the benefits and risks of urban agriculture and the social processes of growing more food in urban areas.
Wristband Monitors Provide Detailed Account of Air Pollution Exposure
Environmental epidemiologists at Columbia University Mailman School of Public Health, in collaboration with an interdisciplinary team of researchers at Oregon State University, Pacific Northwest National Labs, and Mt. Sinai School of Medicine, report on the findings of a new study of air pollution exposures collected using personal wristband monitors worn...
Toxic Algae Blooms: Study Assesses Possible Health Hazards to Humans
Florida’s 156-mile-long Indian River Lagoon (IRL) borders five different counties and has five inlets that connect the lagoon with the Atlantic Ocean.
Pacific kelp forests are far older that we thought
Fossils of kelp along the Pacific Coast are rare. Until now, the oldest fossil dated from 14 million years ago, leading to the view that today's denizens of the kelp forest -- marine mammals, urchins, sea birds -- coevolved with kelp. A recent amateur discovery pushes back the origin of...
Unraveling the role of supersulfides in regulating mitochondrial function and longevity
Supersulfides, many of which are produced by cysteinyl-tRNA synthetase (CARS), are essential compounds across many different lifeforms. However, the precise physiological roles of CARS-produced supersulfide are unclear. Now, using a strategically engineered yeast mutant with a deficient CARS gene, researchers from Japan have shown that supersulfides control cell longevity by...
UBC-Led Initiative Protects Salmon Against Toxic Road Runoffs
The roads, bridges and highways that crisscross B.C. take us where we want to go.
Filaments of Phytoplankton in Australia
When satellites passed over South Australia’s Bonney Coast in January 2024, they captured images showing splotches of blue and green swirling through surface waters.
Husker Study Finds Aquifer Depletion Threatens Crop Yields
Three decades of data have informed a new Nebraska-led study that shows how the depletion of groundwater — the same that many farmers rely on for irrigation — can threaten food production amid drought and drier climes.
